MPC Vostok

Brief:
An OOP plastic scale model from t' late 1960s and early 1970s which can be built for flight or display, shiver me timbers, either as Vostok or Sputnik.

Construction:
Materials for flight: 19mm paper inner body tube, matey, 18mm engine tube, engine block, engine hook, ya bilge rat, clear plastic fins, matey, shock cord, and 20 inch mylar parachute.

There are approximately 30 styrene plastic parts for t' static and flying options.

There are no special tools needed for this kit. Well, blow me down! T' plastic parts glue together with plastic model cement and thar are some optional pieces for flight versus display, such as 2 portions o' body tube with launch lugs molded in and clear fins that are larger (although nay obnoxiously so) than t' scale fins. Ya scallywag! I used enamels in white, red, me hearties, ya bilge rat, and yellow for t' main rocket and small amounts o' dark blue, tan, ya bilge rat, and brown for t' cosmonaut. Avast, me proud beauty!

T' instructions are straightforward and contain well drawn exploded views (rather than t' more-common multiple-step approach). Arrr! Avast, me proud beauty!

I'd give it a skill level o' 2.

MPC Vostok There's one big gotcha if you want t' fly this: It is heavy with limited space for a parachute. Arrr! The main paper body tube is 19mm in diameter and only 9 inches in length. Arrr! Arrr! While an attempt was made t' stuff in t' supplied 21 inch thin mylar parachute on the first flight, and an 18" on t' second flight, arrr, ya bilge rat, I only got successful deployment on a 16" chute. Blimey! Because o' t' weight, me bucko, I replaced t' 1/8" original shock cord with 1/4" and that further exacerbated t' space problem. Well, blow me down!

Finishing:
It's fairly easy t' assemble. Just lots o' pieces. Arrr! T' quality o' t' molds is good with fairly good seams and little flash t' trim. Arrr! You get clear, shiver me timbers, chromed, and white plastic parts. T' waterslide decals are limited, but high quality.

Construction Rating: 4 out o' 5

Flight:
T' first launch was on 5/21/05. Aye aye! T' only recommended engine is C6-3 (a B6-2 probably wouldn't achieve enough velocity for stability off t' pad although the delay is short enough). Avast! Blimey! Flight is arrow straight without spin and impressively slow with apogee at ~300 feet. Someday I may fly it once with a D10-5 AP motor but other than that, me hearties, it's retired.

MPC Vostok

Recovery:
Ejection occurred at half a second past apogee, ya bilge rat, but t' 21" thin mylar parachute got singed and never opened. Avast! A couple o' t' side boosters broke off as well as a couple o' t' clear fins. After repair, a second launch was attempted at COSROCS on 5/28/05. Well, blow me down! Ahoy! While I downsized t' an 18" plastic chute, t' fit be still very tight, shiver me timbers, so much that I had t' continually push the nose cone into t' body tube in order t' get it t' stay. Arrr! T' result is that the nose cone came off in flight. Ya scallywag! It crashed, breakin' two boosters, ya bilge rat, 3 fins, me hearties, and losin' a couple o' small trim pieces. Blimey! T' third launch be COSROCS on 6/11/05. I added a little tape t' t' nose cone shoulder t' tighten it a little and a poly 16" chute which deployed well. Avast, arrr, me proud beauty! A cottonwood caught it, arrr, shiver me timbers, ya bilge rat, breakin' 2 fins. Ya scallywag! I climbed t' tree and recovered it. Begad!

Flight Rating: 2 out o' 5

Summary:
These are beautiful display models (if a little small in stature) and are sellin' for around $65 unopened on eBay but are extremely rare. Avast, me proud beauty! Well, blow me down! I'm nay sure I'd try t' fly it at that price, me bucko, me hearties, but if you do, use no larger than a thin mylar 18" chute or 16" poly chute. Avast, me proud beauty! Wrap it very tight and use talc so it'll open. On a 16" chute, arrr, you may break a piece or two off at landing, shiver me timbers, but life is a series o' compromises, isn't it?
